Nanobiotechnology in Agriculture: Use of Nanomaterials To Promote Plant Growth and Stress Tolerance.
Abstrak
Sustainable agriculture is a key component of the effort to meet the increased food demand of a rapidly increasing global population. Nanobiotechnology is a promising tool for sustainable agriculture. However, rather than acting as nano-carriers, some nanoparticles (NPs) inherently enhance plant growth and stress tolerance. This biological role of nanoparticles depends on their physiochemical properties, application method (foliar delivery, hydroponics, soil) and the applied concentration. Here we review the effects of the different types, properties and concentrations of nanoparticles on plant growth and on various abiotic (salinity, drought, heat, high light, and heavy metals) and biotic (pathogens and herbivores) stresses. The ability of nanoparticles to stimulate plant growth by positive effects on seed germination, photosynthesis, root or shoot growth, and biomass or grain yield is also considered. The information presented herein will allow researchers within and outside the plant nanobiotechnology field to better select the appropriate nanoparticles as starting materials in agricultural applications. Ultimately, a shift from testing/utilizing existing nanoparticles to designing specific nanoparticles based on agriculture needs will facilitate the use of nanotechnology in sustainable agriculture.
